Introduction
About the LaserAce 1000 rangefinder
The LaserAce 1000 rangefinder is a three-dimensional (3D) laser rangefinder that
enables you to measure points using a simple “point and shoot” workflow.
Measurements and calculations are displayed on the back-lit LCD panel.
The rangefinder incorporates a pulsed laser distance meter and compass. Use the
sighting scope to aim and measure range, vertical, and horizontal angles to passive
targets up to 150 m (500 feet) away. Using a reflective foil target, you can measure
targets up to 600 m (2000 feet) away.
You can connect the rangefinder to a Trimble Mapping & GIS handheld using
Bluetooth wireless technology and then automatically output the rangefinder data to
the GPS field software running on the handheld. This is especially useful when you are
using the rangefinder to map assets using offset positions, for example for assets that
are located in difficult GNSS environments or in difficult-to-access areas, such as on a
traffic island in a busy highway.
The rangefinder is Class 1 eye safe (FDA/IEC). Lightweight and compact, it is designed
for all-day field work.
The LaserAce 1000 rangefinder comes in three varieties, depending on the firmware
version that is installed. These are described below.
LaserAce 1000 rangefinder with GIS firmware
The LaserAce 1000 rangefinder with GIS firmware incorporates a pulsed laser distance
meter, inclinometer, and compass. Use this version of the rangefinder to perform the
following calculations:
•
Distance rangefinder measurement
•
Subtended distance (diameter measurement)
•
Area and volume calculation
•
Three-point heighting
•
Cable detection using rapid fire mode
Note – When running the GIS firmware, the LaserAce 1000 rangefinder does not provide a
“Save” function for saving data.
LaserAce 1000 rangefinder with hypsometer firmware
The LaserAce 1000 rangefinder with hypsometer firmware is designed to help foresters
easily and efficiently measure the height of a tree, its diameter (at any height), simple or
“taper” log volumes, and tree lean. Use this version of the rangefinder to perform the
following calculations:
12
•
Measuring reflectorless ranges up to 150 m / 500 ft
•
Brush filter mode ( for use with reflective tape)

•
Three-point height measurement
•
Diameter measurement
•
Log volumes
•
Plot sampling
The hypsometer firmware automatically carries out mathematical calculations for
instant field results. The rangefinder stores up to 2000 results for later viewing and
downloading to a computer using a Bluetooth wireless connection.
LaserAce 1000 rangefinder with burden finder firmware
The LaserAce 1000 rangefinder with burden finder firmware is designed to accurately
determine rock face or blast hole burdens in three easy steps. It also provides an
internal digital compass for measuring face width.
Use this version of the rangefinder to:
•
Set up drill parameters such as drill angle, collar to crest offset, and minimum
burden.
•
Set up bench details such as the crest and toe of the profile.
•
Shoot the profile of the rock face and obtain instant burden and depth
measurements based on the drill parameters and bench details you have
entered.
•
Measure the width of the rock face.
The rangefinder stores burden and depath table measurements for later viewing,
editing, and recalculating. The stored data can later be downloaded to a computer
using a Bluetooth wireless connection.

General guidelines for using the rangefinder
C
WARNING – The LaserAce 1000 rangefinder has a Class 1 eye safe (FDA/IEC) rating.
However, you should take care when using the rangefinder to minimize the risk of
damage to your eyesight or that of other people’s. Specifically:
– Do not direct the rangefinder toward the sun or another high power, infrared light
source.
– Do not unnecessarily look into the transmitter lens of the rangefinder.
– Do not point the rangefinder directly at other people’s eyes, especially if they are using
binoculars.
Hold the rangefinder in the right hand, like a camcorder, by
putting your fingers through the handstrap and aiming the
lenses at the target. Trimble recommends using the right eye to
look through the eyepiece while keeping the left eye open to
make identifying the correct target easier.
Identify the target by sighting the target through the telescopic
sighting scope. If a valid range or measurement is observed, a
beep sounds.
Obtaining optimal range
The maximum range observable can vary due to:
•
size of the target (with respect to the laser beam footprint, see below)
•
environmental conditions
For example, longer ranges are possible in overcast/dark conditions, but bright
sunlight results in shorter ranges. Rain or snow will result in shorter ranges.
To obtain optimal ranges:
•
Use good reflective targets such as light-colored rocks, light-colored masonry
and stone, and reflective traffic signs, vehicle reflectors, and foils.
•
Try to observe targets that are in the shade or away from prevailing sunlight.
•
Use targets that are the same size or larger than the laser beam footprint:
Distance to Target
Typical Dimension of the Measuring Beam (footprint)
100 m (328 ft)
25 cm (10 in)
200 m (656 ft)
50 cm (19.6 in)
300 m (984 ft)
75 cm (29.5 in)
400 m (1312 ft)
100 cm (39 in)
Note – The rangefinder is not designed for use with reflectors at ranges below 100 m (328
in). Only use reflectors for ranges above 150 m (492 ft).

Getting Started
Setting the magnetic declination
Note – When the rangefinder is shipped from the factory, the magnetic declination is set to
zero. Before you begin using the rangefinder, you may need to enter a magnetic declination
for your geographic area. If you are using the Trimble TerraSync™ software with default
Units settings you do not need to set the magnetic declination, and should leave it as zero.
You can check these settings in the Units form, in the Setup screen. If the North Reference is
set to True and the Magnetic Declination is set to Auto then the TerraSync software will
find the declination and apply it to the offset measurements automatically.
The earth is completely surrounded by a magnetic field, and any unobstructed
magnetized object, or North-seeking compass, will orient itself with the magnetic
North and South poles if free to rotate. Magnetic declination (also known as magnetic
variation) is the difference in the bearing, or angle, from your position to true North
(also known as the North Pole) and magnetic North, which is located somewhere in
Northern Canada.
Magnetic declination varies significantly from location to location around the world
and also varies slightly from year to year. It is important to find out the correct
magnetic declination for your area so that the calculations the unit performs are
correct.
Magnetic declination is stated as a number. To find out the magnetic declination for
your location, do one of the following:
•
scale it from a chart
•
calculate it from accurately known geographic coordinate points
•
calculate it using the National Oceanic and Atmospheric Administration
(NOAA) website. Go to www.ngdc.noaa.gov/geomagmodels/Declination.jsp and
then enter your zip code or the latitude and longitude values for your location.
To enter the magnetic declination:
1.
From the main menu screen, select Setup.
2.
Select Configuration.
3.
Select Compass.
4.
Select Declination Angle.
5.
Enter the angle and then select whether the angle is east or west.

Note – The slower and steadier the rotation the better chance of getting an accurate
calibration. For each of the three rotation procedures listed below, each involves two
rotations which should take approximately one minute total to complete (two rotations x
30 seconds each). Any bumps in motion could cause errors in the pitch and roll as they are
seen as acceleration on the sensors.

This chapter describes how to set preferences
and take measurements using the rangefinder
with the GIS firmware installed.
All of the measurement types described in this
chapter can also be used to record offset GPS
positions, for example when you cannot access
the asset that you want to record the GPS
position for, or when the asset is located in a poor
GPS environment.
Note – The LaserAce 1000 rangefinder’s internal
compass is sensitive to many factors, including
changing the battery and changes in the
environment. Trimble recommends calibrating the
internal compass at the start of each data
collection session. For more information, see

Managing profiles
The Hole Details menu provides options for managing profiles stored on the
rangefinder.
Reviewing/recalculating an existing profile
The burden and depth table results are stored in the rangefinder’s internal memory. As
each profile has a face number and hole number, each unique profile can be recalled
and the burden and depth table reviewed.

The rangefinder then displays the burden and depth table for the profile you
requested.
3.
To recalculate the burden and depth table for a profile, return to the Hole Details
menu and change the drill angle, collar to crest offset and minimum burden.
4.
Follow steps 1 and 2 above to review the profile. The burden and depth table has
been recalculated based on the new parameters you entered.
